Learning Methods & Best Practices

1. Active Learning Approach

Theory → Practice Cycle

Step 1: Read & Understand (20%)

Đọc lesson content
Take notes (handwritten or digital)
Highlight key concepts
List questions

Step 2: Code Along (30%)

Type every example yourself
Don't copy-paste
Experiment with variations
Break things intentionally

Step 3: Practice Exercises (30%)

Complete all exercises
Don't look at solutions immediately
Debug errors yourself
Google when stuck (15-minute rule)

Step 4: Build Projects (20%)

Apply concepts to projects
Add extra features
Refactor và optimize
Deploy to production

2. Spaced Repetition

Daily Review:

Spend 15 minutes reviewing previous day
Quick quiz yourself
Revisit tricky concepts

Weekly Review:

Dedicate 1-2 hours Sunday/Saturday
Review entire week's content
Identify weak areas
Redo challenging exercises

Monthly Review:

Full module review
Build mini-project integrating all concepts
Update personal notes/cheatsheet

3. Deliberate Practice

Focus Areas:

Identify weak spots
Practice specifically those
Track improvement
Celebrate progress

Practice Techniques:

Pomodoro: 25 min focus + 5 min break
Time-boxing: Allocate specific time per task
Pair programming: Work with peers (virtual)

4. Project-Based Learning

Build Variations:
Cho mỗi project trong course, build thêm:

Different domain (e.g., e-commerce → bookstore)
Extra features (wishlists, reviews)
Mobile API version
Admin dashboard

Portfolio Projects:
Parallel với course, build 2-3 personal projects:

Something you're passionate about
Solves real problem
Can show employers
Deploy publicly

5. Learning Resources Integration

Documentation First:

Always read official Django docs
Check DRF docs for API features
Reference is your friend

Stack Overflow Smart:

Search before asking
Read multiple answers
Understand why solution works
Contribute answers when you can

Video Tutorials:

Supplement, not replace
Watch at 1.5x speed
Take notes
Practice afterwards

Books:

"Two Scoops of Django" (Best practices)
"High Performance Django" (Optimization)
"Django for APIs" (DRF focus)

6. Code Quality Habits

From Day One:

Write docstrings
Add type hints
Follow PEP 8 (use black)
Write tests
Use meaningful names
Comment complex logic

Code Review:

Review own code next day
Ask for peer reviews
Review others' code (GitHub)

7. Note-Taking System

Digital Notes:

Use Notion, Obsidian, or Markdown files
Organize by module
Add code snippets
Link related concepts

Personal Cheatsheet:
Build your own reference:

Common patterns
Gotchas to avoid
Useful commands
Code templates

8. Accountability & Motivation

Public Commitment:

Share goals on social media
Blog about learning journey
Tweet progress (#100DaysOfCode)
Join study groups

Track Progress:

GitHub contributions calendar
Learning journal
Project checklist
Skill self-assessment

Rewards System:

After each module: Watch movie
After each project: Buy something nice
After completion: Celebrate big!
